Description

Technical Field

[0001] This utility model relates to the field of pipe fitting production technology, specifically to a cooling and dust prevention device for the molten iron monitoring probe of a centrifuge used in ductile iron pipe production. Background Technology

[0002] When centrifugally casting ductile iron pipes, the molten iron should immediately descend after filling the socket. The molten iron detection system is set with a molten iron monitoring probe on the core frame to detect the time it takes for the molten iron to reach the socket. Then, by setting parameters to delay the descent time, the centrifugal casting machine can automatically pour the molten iron into the socket, accurately control the thickness of the cast pipe socket, and rigorously guide the centrifugal casting process of ductile iron pipes.

[0003] However, due to the high operating temperature of the molten iron monitoring probe, its service life is easily affected. At the same time, the large amount of dust floating during operation can contaminate the lens, easily causing errors in the monitoring data and affecting subsequent production processes.

[0004] In view of the above-mentioned defects, the creator of this utility model has finally obtained this utility model after a long period of research and practice. Utility Model Content

[0026] The present invention relates to a cooling and dustproof device for a molten iron monitoring probe in a centrifuge used for ductile iron pipe production. The device includes a probe lens 1, a probe housing 2, a venting sleeve 3, a mounting plate 4, and a connector 5. The probe housing 2 contains a fixed cavity 21 and a placement cavity 22. The detection end of the probe lens 1 is located within the placement cavity 22, and a first flow gap is provided between the inner wall of the placement cavity 22 and the probe lens 1. The probe housing 2 has a detection hole 23 corresponding to the detection end, ensuring that the probe lens 1 monitors the molten iron condition through the detection hole 23. The fixed end of the probe lens 1 is connected to the venting sleeve 3 and the mounting plate. 4. The probe lens 1 is fixedly installed in the fixed cavity 21, thereby fixing the probe lens 1 in the probe housing 2. A second flow gap is provided between the inner wall of the fixed cavity 21 and the probe lens 1. The mounting plate 4 is provided with an air tube hole 41 and an optical fiber hole 42.

The first flow gap and the second flow gap are connected through the vent hole 31.

[0027] The cooling airflow generated by the air pipe passes through the second flow gap, the vent 31, the first flow gap, and is discharged through the detection hole 23. The airflow discharged through the detection hole 23 also cleans the dust near the detection hole 23 and the detection end, thereby achieving both cooling and dust prevention.

[0028] Preferably, both the fixing cavity 21 and the placement cavity 22 are cylindrical cavities, so that the first flow gap and the second flow gap are both formed into annular flow spaces surrounding the probe lens 1, which facilitates the overall cooling of the probe lens 1.

[0029] The fixed end of the probe lens 1 is provided with a fixing ring 11. The cross-sectional diameter of the fixing cavity 21 is larger than the cross-sectional diameter of the placement cavity 22 to form a boss. The ventilation sleeve 3 is disposed between the fixing ring 11 and the boss, thereby fixing the position of the ventilation sleeve 3.

[0030] The mounting plate 4 is fixedly disposed at one end of the fixed cavity 21, and the mounting plate 4 abuts against the fixed end of the probe lens 1, so that the fixing ring 11 is disposed between the mounting plate 4 and the ventilation sleeve 3, thereby fixing the position of the probe lens 1 inside the probe cover 2.

An air path is formed by the first flow gap and the second flow gap, integrating the optical fiber assembly and the dust removal assembly. It can achieve dust blowing and cooling while ensuring normal probe monitoring, and is easy to clean and maintain.

A plurality of ventilation holes 31 are evenly distributed in a ring around the socket 32 ​​to achieve uniform transition of airflow from the second flow gap and the first flow gap.

[0034] Preferably, the axis of the vent hole 31 is parallel to the axis of the sleeve hole 32. The boss is designed to ensure that there is sufficient flow space for both the vent hole 31 and the first flow gap. The end of the vent sleeve 3 near the first flow gap is provided with a flow groove 33. The flow groove 33 is a circular cross-sectional groove extending along the axis of the vent sleeve 3. The cross-sectional diameter of the flow groove 33 is larger than the cross-sectional diameter of the placement cavity 22.

[0035] The end of the venting sleeve 3 away from the first flow gap is provided with a flow ring groove 34. The flow ring groove 34 is circular and is connected to the end of each of the vent holes 31, so as to facilitate the airflow of the second flow gap to flow evenly into the vent holes 31.

[0038] The end of the fixed cavity 21 is provided with a first positioning groove 24, which is an annular groove. The mounting plate 4 is provided with a first positioning ring 43, which is disposed in the first positioning groove 24, thereby fixing the position of the mounting plate 4 on the probe cover 2.

[0039] The mounting plate 4 is provided with a second positioning groove, which is an annular groove. The connector 5 is provided with a second positioning ring, which is disposed in the second positioning groove, thereby fixing the position between the connector 5 and the mounting plate 4.

[0040] The first positioning ring 43, the second positioning groove and the mounting plate 4 are all coaxially arranged, and the fiber optic hole 42 is located at the center of the mounting plate 4, thereby ensuring the smooth connection between the fiber optic cable and the probe lens 1.

[0041] The probe housing 2 is provided with a first mounting hole 25, the mounting plate 4 is provided with a second mounting hole 44, and the connector 5 is provided with a third mounting hole 51.
